Speed comes as a factor of our perception, it is part of the design process. The trees ling a road can be either a barrier or an opening framing a view depending of our speed. On the side of the road tghe space between trees can become narrower and narrower as our speed increases. The pedestrian does not share the same experience with the car driver. Here comes back the notion of scale. As usual we have to make a decision about how do we would like our visitors to have an experience.
